gearing question, what would you do?

[mineralgrey01gt]

well I just got done with my rebuild and wouldnt mind having a little more bottom end, but then again it doesnt hook up well with the 18's on it now. I never ran it with my stock 20" tires yet. What would you do for gearing? Im still on stock gearing i think, i know the front is a 15 tooth. Everywhere I ride is mostly short straight aways and tight trails, occasionally we hit a sand pit.

14/39 for stock motor and 20inch tires is perfect

so pretty much the 15/39 is good for 18" tires? My motor isnt stock, im just trying to decide to drop it to a 14 or not pretty much.

I have basically the same set up and I run a 15-36 on 18’’ hole shots. I would like to try a 15-35 combo.

This may help

that 15/35 doesnt look bad, 74.5 roughly at the top of 5th
